,SOIL-PIPE AND ROOF CONNECTION.

SPECIFICATION forming part of Letters Patent No. 621,320, dated March21, 1899.

Application filed December 3, 1897. Serial No. 660,701. (No model.)

Aing a weatherproof joint between the roofing of houses or buildings andthe soil pipe, stack,

or other flue providing an escape or vent, and which will obviate amolten, putty, or like joint, and which will not be affected bycontraction and expansion and fulfil the requirements presently to bereferred to..

Certain requirements provide that the projecting portion of the soilpipe or stack above the roof shall be of larger diameter than the inneror main portion, and to meet these conditions different sizes of pipeare generally employed and require a molten or like joint between them.A purpose of this invention is to have the inner and outer portions ofthe pipe of different diameters and integrallyT formed, therebyobviating the' necessity for the usual joint and simplifying theconstruction and materially reducing the cost. The lower portion of theenlarged section of the pipe encircles the upper portion of the smallersection and overlaps the upper end of the roof-flanges, which latter issnugly received into the space surrounded by the depending portion ofthe upper or enlarged section, as will be describedat length farther on.

For a full understanding of the merits and -advantages of the inventionreference is to be had to the accompanying drawings and the followingdescription.

The improvement is susceptible of various changes in the form,proportion, and the Vminor details of construction without departingfrom the principle or sacrificing any of the advantages thereof, and toa full disclosure of the invention an adaptation thereof is shown in theaccompanying drawings, in which- Figure lis an elevation of the upperlength of a soil pipe, stack, or flue constructed in accordance withthis invention, showing it inA operative relation. Fig. 2 is a verticalcentrai section. Fig. 3 is a detail section thereof, on a larger scale,and disassociated from the roof-liange and other parts.

Corresponding and like parts are referred to in the followingdescription and indicated in the several views of the drawings by thesame reference characters.

The pipe, stack, or flue is composed of parts l and 2, the part l beingof larger diameter than the part 2 and being the upper or outer element.rPhe part 2 is the inner or lower element because it does not projectbeyond the roof 3 and is of less diameter than the upper part l. Theseparts 1 and 2 are inte grally formed, and the lower portion of the outerpart l surrounds the upper or contiguous portion of the part 2,inclosing a space 4, which receives the upper end of the roofiange 5,the latter being of ordinary construe-- tion and having'its base securedto the sheathing and overlapped by the shingles or slates in the usualmanner. The pendent portion 6 surrounds the roof-flange 5 at its upperend and excludes rain and provides a weather'- tight joint withoutrequiring the use of putty,

calking, or other material, and the parts can contract and expandwithout danger of starting or opening seams and causing leaks. The upperpart 1 lnay be suitably ornamented, thereby giving a nished appearanceto the projecting portion of the pipe.

The base of the roof-ange may be straight or angling, according to thepitch of the roof, and in metal5 roofing it may be a collar soldered atits lower end to the metal covering. This pipe does not require anyspecial fitting to the roof and can be placed in position by thecarpenter, tinner, or roofer, thereby obviating the necessity for theplumber to go upon the roof when placing the soil pipe or stack inposition.

At this point it is to be observed that the space confined between thependent dan-ge 6 and the lower pipe-section 2 is formed by providing theupper end of said lower pipe-section with an upwardly -inclined andoutwardly-deflected web, which is joined to the larger pipe-section 1near the lower end of the latter, and by reason of having the said webupwardly inclined and disposed adjacent the roof-flange 5 is permittedto snugly em- ICO brace the lower pipe-section 2 and also to have itsupper end rest against the said inclined outwardly-deflected web,thereby insuringa proper support of the soil-pipe on the roof -ange anda thoroughly weather-tight connection between these parts.

Having thus described the invention, what is claimed as new isl. Asoil-pipe having separate upper and lower concentric sections,respectively, of different diameters, and the lower section provided atits upper end with an upwardly-inelined and outwardly-deflected Webjoined to the larger upper pipe-section near the lower end of thelatter` and forming an intervening space between the contiguous ends ofthe two sections, said lower pipe-section being adapted to snuglyregister within a roof-lian ge, and the Aintervening space between saidsections permitting the roof-fiange to extend to a point with its upperend resting against said deected web, substantially as described. g

2. In a soil pipe, stack or Iiue, a length comprising upper and lowerparts integrally formed and of diierent diameters, the upper part beingthe larger and having its lower portion surrounding the upper portion ofthe lower part and forming a space to receive the upper end of aroof-flange, substantially as set forth.

In testimony that I claim the foregoing as my own I have hereto aiixedmy signature in the presence of two witnesses.

JAMES W. BROWN.
